To all 107mm t may concern.'

Be it known that I, THOMAS MIDGLEY, a citizen of the United Statesoi`America, residing at Hampden, in the county of Hampden and State otMassachusetts, have invented certain new and useful Improvements inCore-Handling Apparatus, of which the following is a speciiication.

My invention relates to core holding devices and has for its object aneliective apparatus for positioning and manipulating tire forming cores.This application is a division of my prior application Serial No.459,330, liled April 7, 1921, now Patent Number 1,558,904, issued Get.`27, 1925.

The present invention provides a. machine for effectively raising andlowering the core from a hook on an overhead track, and a device orsupporting` the core during the tire building operation. It alsoprovides a device for moving the core carrying hooi; away from the coreduring the tire building operation.

Additicnal objects, advantages, and features oi. the invention willappear from the construction, arrangement, and combination oi the partsas indicated in the follow ing descriptionl and in the accompanyingdrawings, in which Fig. 1 is a sectional elevation of a tire buildingmachine in which the core handling apparatus is shown in heavy blacklines;

Fig. 2 is a detail top plan thereof showing the hook clamping mechanismpriorto clamping the core carrying hook;

Figs. 3 and l are successively later stages in the same operation;

Fig. 5 is a section substantially on line 5--5 of Fig. l;

Fig. 6 is a section on line G-G of Fig. 1;

Figs. 7 and 8 are partial views similar to Fig. 6, illustratingsuccessive stages in more ing the core into position tor clamping themechanism to act on itg and Figs. 9, 10,. and i1 are diagrammatic viewsshowing how the core carrying hook is moved out ot operation prior tothe shaping of the tire.

Uarried by the trame or" the machine are bearings in which ris journaledthe main shaft 29 carrying cams 30 and 31 which will be referred to.This shaft may be driven as through a worm and wheel 82 from a suit'-table source of power, preferably through a clutch mechanism 33 of thetype which, when the control lever is actuated, will permit themechanism to run through one complete Cycle and will then cause it tostop. Such clutches are old and their construction need not be furtherdescribed.

Cores 35 are supplied to the machine in any desired or convenient way.In the preferred embodiment of my invention, however, I contemplatesupplying the cores on hooks 36 connected by swivels37 to carriages 38ruiming on a track 39, and provide mechanism which will now be describedfor supporting the lcore and temporarily removing the hook from aposition in which it would interfere with the operation oit the devicesfor shaping the fabric to the sides of the core.V `When the core isdelivered to the machine it is stopped approximately in position eitherby hand or automatically, as by providing track 39 with a depression 39in which carriage 38 will lodge, and is then grasped by rollers 40, 41,i2, and 113, each oi these having concave surfaces conforming to theoutside of the core. Rolls 40 and 41 are each rotatably mounted on anarm lil pivoted 4:5 to a bracketv 46 on thetrame ot the machine. An eari7 oneach arm all contacts with .a ledge on the bracket 16 to limit thedownward movement of the rolls, an adjustable stop a9, on ledge d8limiting` the upward movement. The rolls Y' are ino-ved downward bytheir own weight and upward by contact with the core, which is raisedupwardly to free its hook by rolls d2 and 4:3.

These latter rolls are rotatably mounted on a slide 50., which isprovided with an opening 51 enabling it to clear the shaft 29, andlwhich runs on bearings suitably secured in machine frame. A cam roll 53carried by the slide 50 lits in a cam groove 54C in one tace of cam 30previously mentioned. In order to adjust accurately the position of theslide 50, cam roll 53 is preferably mounted on an arm 55 pivoted at 56to the slide and having' at its otherend a hole 57 through which passesa threaded rod 58 secured to a bracket 59 on the slide. lBy this meansthe arm 55 can be rotated on its pivot 56 and held by nuts 60 on the rodin its adjusted position, in order to locate accurately theverticalposition of the cam to be seized by the rolls and preferablybefore rolls and i3 start to raise the core.

oil the hook, the swivel of the hooi; is g faspcd by clamping meanscomprising opposed semi-circular clamping jaws (it) and 6i, eachslidably mounted on a semi-circirlar dove-tailed guide 62 on slides 63and resliiectively.

Slide 6i is mounted for rec-iprocation in guides 65 carried by theframeof the machine, and is provided with a raclr 66v meshing with a. pinion67 on a short shaft 63 driven througli bevel gears 69 from a verticalshaft 70. rihis latter shaft receives oscillatory rotation through bevelgears 71 from a, shaft 72' carrying an arm 7 3 on which is pivoted a camroll 7d running in a cam groove on the cylindrical surface of cam 3l.This cam, acting through the intermediate mechanism described, sei'vesto move slide 64 toward' and away from the center of the machine,whereby clamp 6l is caused to move into andV out of clamping position.

Clamp member 60 is moved into and out of clamping positioncoincidentally with clamp member 6l by mechanism operated by the motionof slide 6st. This slide carries an abutment which., when the slide ismoved towards the center of the machine, impinges against a lever 76pivoted at 77 to a bracket 73 secured to the guides 79S in which slide63 reciprocates. The end of lever 76 opposite that against whichabutment 75 contacts is forked as at 80 tol receive a pin 3l mounted onYslide 63. Slide 63 is normally held in its retracted or non-clampingposition as shown in Fig. Q'by a spring 82 secured at one end to theslide and at the other to a stationary part of the machine, but as slide64 is moved toward clamping position the lever 76 acts through pin 81 tomove slide 63 into clamping position against the tension of the spring.

Clamps 60 and 6l have mating clamping surfaces which are shapedl toconformA to the swivel position of the core supporting ioolr, and arevadapted for rotation on their dove-tailguides 62 in order to swing thehook, when the latter is freed. by the raising of the core from its.position transverse te the plane of the core (Figs. I, 6, and 8) to aposit-ion substantially parallel to the plane of the core (Figs. t, 5,l0, and 11). For this purpose clamping member 6l is provided with gearteeth which mesh with a. segmental gear 86 on a shaft 87 journaled inslide 64e and connected by gearing 88 with a horizontal sha-ft 89. Thisshaft is splined or keyed as at 90 to a sleeve 91 journaled in a bearing92 supA ported by the frame. The sleeve 9i pis connected by gearing 93with a vertical shaft 94- Which in turn is connected through gearingwith an arm 96 rotatably mounted on themain frame and having a cam rolldii ruiming inA n cani groove Sit) in the end face of cam 3l.. By theabove train ofV niecl'ianism the clamping member 6l., and throughcontact with it clamping member GO, will be rotatedl so as to turn thehoot: 36' substantially 90O on its swivel, or from the position of Fig.D to that of Fig. l0.

Shaft 87 which carries the segmental gear 86 alsoY carries an arm 100serving to move the bool; from the full to the dotted' line position ofFig. t1 or the full line position shown in Figs. 4 and 5' during the`latter part of the rotating move ment of the clamping members. After thefabric shaping mechanism has completed its operation the hooi: 36 isswung bacia into its original position in which it can support the coreby a reversal of the opera` tions previously described for swinging thehool': into inoperative position. Rolls #"3 and r3 are then caused todescend, thus repositioning thel core in place upon the hoolr. Duringpart of this lowering of the core, rolls ,40 and 4l follow it doivnbygravity, their flanged sides furnishing lateral support for the core.

The general operation of the core handling machine is as follows: A.core carried by a hool'r is brought into place ready to be grasped bythe positioning rolls, and the swivel of the hoolr is seized by clampingmembers 60 andl 61. Rolls 4t2 and 4113 are then caused. to rise, liftingthe core against rolls 40 and tl so that the core is held in a centralposition forA operation upon by 'the fabric shaping mechanism. rEhevertical motion of the core may shift the hooll from the full to thedotted line position of Fig. 9,. depending upon the shape of the hoolc.As the core is grasped by its positioningv rolls the clamiliing members66 and 6l are rotated, swinging the hook from the dotted line posit-ionof Fig. 9 to the position shown in Fig. l0 and in full lines in Fig.1:1. As, or even before, this motion is completed armv 100 contacts withthe hoolr andv swings it tothe dot-ted line position of Fig. 1lv or theposition shown in Fig. 5, thus leaving the. sides of the coro free forthe, operation of the fabric shaping mechanism.

The core handling apparatus is adapted for use in connection with anyform of tire building opera-tion. For example, the lifting and guidingrolls may rotatably support the core so that it may be operated upon bythe usual type of spinning or stitching rolls. In this case the corecould erotated by a friction roll contacting with its surface, and itwould not be necessary to swing' the hool completely out of the,l

way as where it is desired to conform the fabric to the core bycircumferentially simultaneous pressure.

Having thus described my invention, I claim:
